Intake manifold EML
Intake manifold on my a220cdi w176 has been changed because engine light came on for code:
P200A21The charge movement flap (cylinder bank 1) has a malfunction.The signal amplitude is less than the minimum amplitude.
After a new intake manifold and actuator was fitted and codes cleared after a week the EML came back on with the same fault. The flaps are moving and the actuator can be actuated from diagnostic machine. Do they need to be taught in or are they usually plug and play? Its stressing me out 😫
